A spindle'2 upwardly extends spindle 8 is made to engage.

throughz-the table. The spindle is of the relatively high speed type having a plurality of cutter knives secured thereto. In shaper heads carrying this type of cutter head wood of varying degrees of hardness may be shaped and finished irrespective of thecharacter or position ofthe grain and a uniform quality or finish be imparted thereto.

. HThe device may be adapted to any form of shaper table, A supporting clamp 3 is provided having a top surface a that is made to engage one of the surfaces of the table and a lug 5' is made toeXtend in spaced relation with the surface 1in order that the table '1' may be madeto extend therebetween. The

supporting vamp is secured toithe table by any suitable fastening means, as by a set screw 6.1{A suitable bearing 7 is placed within the clamp into which the vertical I Suitable adjusting-and locking nuts 9 are placed at either end of the bearing 7 to position and maintain the spindle at the proper working :height relative'to the table 1 and the shaper spindle 2. lVhenproperly adjusted the spindle 8 and bearing 7 may be rotated relative to the clamp 3. A platform 10 carrying a counterweight 11 is secured to the upper end of the spindle 8. The connection between the platform 10 and the spind1e8 being made through the'medium of a horizontal pin 12. This permits ofa raising or tilting of the platform 10 relative to that of the spindle A counterweight 11 is adjustably posi- --tioned aboutthe free end llof the platform. An arm or frame 15 is removably secured to the platform 10 by any suitable fastening :means, "as by fastening elements 16. The arm or frame 15 may be made integral with the platform 10 when so desired; It is desirable to raise and lower the warm 15 fora limited amount only, to permit 'the placing of the piece to be finished thereunder and-it is also desirable to raise and lower'the arm a greater amount to facilitate the placingof the form. I place upon the arm a positioning yoke 17' that may be positioned along the arm and secured thereto, by the fastening element 18. Depending from the yoke 17 are adjustable arms 19. Slots 20 being disposed within the arm to position the same relative to the yoke. When the desired position is secured the same is clamped relative to the yoke by the adjustable clamping fastening 21. A horizontally disposed pin 22 is disposed the lower end of the arm 19 upon which a cam 23 is secured. The pin 22 is partially rotated through the hand lever 2 1. The positioning of the hand lever 24 engagesthe'cam 23 with the upper surface of the table 1,-and in doing so raises the arm 15. A vertical spindle bearing 25 is disposedthe outer end of the arm 15 and a supporting pin 26 is disposed therein. The supporting pin 26 having a bearing head 27 disposed its upper end to maintain the same in place and to prevent the downwardpas-l sage of the pin 26 through the bearing 25; Disposed upon the lower endiof. the pin 26 and immediately beneath the arm 15 is a driven element 28. The driven element 28 is in registerable alignment with and coactswith the driving element '29. Thedriving element 29 is positioned at the lower: end of the shaft 30, the shaft 30 being adapted to being rotated through the hand lever 31. The

shaft 30 carries an adjusting and locking" collar 32 that may be positioned and se-.. 'cured'to the shaft by any suitable fastening means, as by the fastening element A worm 3 1 is disposed upon the shaft 85 which is driven from a. prime mover 86.:'=Because? of a substantial reduction in the speed ratio being desired between the prime mover 36 and the shaft 30, a speed reducer 37 is interposed between the shaft of the prime mover 36 and. the shaft 38, which is adapted for driving the belt 'or chain 39 that coacts with a pulley or sprocket 40 directly mounted upon the shaft 35; The worm 34 coacts with and drives a worm wheel 41. The worm Wheel ll'normally idles upon the shaft 30 and 'dur'-' ing such period theshaft 30 is driven or rotated through the hand manipulation of the crank 31Ywhich is removably secured to the shaft 50, but when it 'isdes'ired to operate :the machine as anautomatic power driven mechanism, the crank 3'1 is IGIIIOVQdi'fIOIIl the shaft 30 and the collar 32 is made-to engage the worm wheel 41, at whichtime ipo'n the driving of the prime mover 36,the device becomes an. automatic power .driven device. A form {l2 which conforms to the shape and sizeand form of the material to be finished is positioned and secured to the driven element 28 and where ajlarge productionisto be made'of a relatively hard material, and

derside of the .pin 26 by threaded engagement .or otherwise,but where few parts are to be made and infrequent changes are required the form 42 may be secured to the driving" lac the same may be directly securedto the unto be finished is placed face down upon the,

table 1, of the shaper and a forcible contact is created between the form 42 and the work to be finished so that the spurs46 are made to engage the back or upper side of the material to be finished. A rubbing collar 47 is positioned above and in spaced relationship with the cutter head 48, so that the form 42 is made to engage with the rubbing collar 47, thus positioning the material to be finished relative to that of the cutter head. The rotation of theform 42 by-hand or power means, rotates the work relative to that of the cutter head and thereby rotates is desired, a flexible cable 49 may be counterthe entire outer peripheral surface or edge of the material to be finished'relative tothat of the cutter head. A hand engaging handle 48A. is placed on the outer end of the arm or frame 15, so that the operator may grasp the same in one hand as he rotates the crank 31 in the other, or, where an automatic feed weighted about a pulley 50. The counterceptible of embodiment in various forms,v all coming within the scope of the claims which follow.

lVhat I claim is:

1.. In a device of the class described, in

combination with a shaper of an attaching clamp adapted. to being removably secured to the shaper table, a spindle vertically disposed within a bearing in the clamp, and a counterweighted frame journaled about a horizontal shaft'disposed within the upper end of the spindle to permit of theraising and lowering of the frame in a vertical plane, a yoke adjustably positioned relative to the arm or frame, means secured to the yoke for raising and lowering the arm or frame relative to the shaper table, arotatable spindle disposed vertically adjacent the free end of the frame, selective means for rotating the spindle, and a removable form disposed at' I the bottom of the spindle.

2. In a device of the class described, in com- Q bination with a shaper of a frame or. arm having attaching means disposed at one'end of the frame to attach the same to the shaper, means associated between the frame and the attaching elements permitting the swinging of the frame in a vertical and in a horizontal plane, an adjustable cam associated between the frame and the attaching elements permitting the swinging of the frame a predetermined amount in a vertical plane and simultaneously in a horizontal plane, a lever for actuating the cam, a driving and a driven element disposed at the free ,end of the frame, selective means for driving the associated driving elements, and a form removably secured to the bottom side of the driven element adapted for engagement with the rubbing collar disposed upon the spindle of the shaper.

3. In a device of the class described, the

combination with a shaper table, a frame detachably attached to one end of the shaper table, means for detachably attaching the 1 frame to the shaper table, a spindle vertically disposed within attaching means and havingits free end forked to rockablyfmaintain the frame upon the spindle, a driving and driven element disposedat the free end of the frame, a counter weight'disposed .at the oppositely disposed end of the frame in order to maintain a proper workingbalance of the associated elements, manually separable means disposed between the driving and driven elements and counter weight for per-' mitting the raising of the frame for a predetermined distance, a form removably dis-' posed upon the bottom of the driven element, and selective means fordriving the-driven element.
